IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 127,@9, dated May 28,1872.

Be it known that I, FISHER AMns FISHER, of Cranford, Union county, Stateof New J ersev, have invented a new and Improved Gas- Burner 5 and Ihereby declare that the following is a full and exact description of theconstruction and operation of the same, reference being had to theannexed drawing and references maliing part of this specitication, inwhich- Figure l is arperspective View. Fig. 2 is a longitudinalelevation, in section, lthrough the center. Fi g. 3 is a section ofcap-piece D, screwing into the burner. Fig. 4 is a section ofthevertical tube A received within the globe B. Fig. 5 is a section ofglobe B and its parts, coutaining tube A and tube C. Fig. 6 is a sectionot' tube C by itself'.

The nature of the invention consists in so constructing the burner,hereinfully described in detail, that the gas in its passage through thesame shall be highly heated and prepared for more perfect combustion,and prevented from rushing out with full force upon the outlet E, andthereby causing, in combination with the heating power, a more perfectcombustion and 'greater illuminating power.

To enable others skilled in the arts toniake and use my burner, Iproceed to describe its construction and operation.

The center tube A is divided in its middle by a cross-partition, i, intotwo compartments, the upper and lower. The lower has a screwthread, h,on its inner surface for attaching' the burner to a bracket-cockconnected with the supply-pipe. This center pipe has also small holes kcommunicating from its lower compartment and entering into theglobe-vessel B, as seen in Fig. 2. There are also similar holes k fromthe upper part of globe-chamber B, into the upper compartment of chamberA, through which gas may pass while the burner is in operation. Vithi-nthe tube A, represented by itself in Fig. 4 and in its working' positionin Fig. 2, within the globe B, there will be seen the tube C, with itsshoulders or hanged periphery resting on the upper end of tube A andjust above holes 7a. Vertically through them; but itwe now grasp by thehand tube and globe B, and screw the globe upward, it will carry alongwith itself tube C and cappiece D, already partly unscrewed, and leavethe shoulder of C on its lower face uncovered, as well as the upper endof tube A, so that the gas in the globe B, passing upward, will passdirectly through the vertical holes in the shoulders C, and take theshorter course through the inner periphery of the cap D, and escapebetween the inner edge of the cap and the outer surface of the tip E,and take fire as it passes into contact with the external air, and soheat the tip E andthe contiguous metal, thereby increasing the amountof' heat and light-in the central jet. This burner is regulated by thescrewing or unscrewing of B, and the tightening or loosening of thescrew-cap D.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination of the several parts of the burner, as B A C D,uniting to prevent direct pressure on the tip E, substantially as setforth.

2. I also claim the construction of the tube C, resting on tube A, andoperated by means of globe B to produce an elevation of the tem peratureof the burner.

3. I also claim the combination of the partition t', hole k, and .hole kfor diverting the current ot'A gas from A to B and from B to A, asdescribed.

4. I also claim the combination ot' the elongated gas-passages through Aand D with the chamber formed by cap D and the sides of tip E,substantially as described.
